This one was just announced to get an anime.
"The story centers on a girl named Maika who gets a job at a cafe where all the waitresses are given certain attributes — such as "tsundere" or "little sister" to embody while serving customers. The manager asks Maika to be the "Do S" (extreme sadist) waitress, so she will have to adopt a dominant and aggressive persona."
Sounds like fun.
